A cold, wet start to spring is making preplant and preemergence herbicide applications challenging to schedule this year. Soybean farmers need to control difficult weeds in a timely manner to preserve yield potential.

Marestail, waterhemp, giant ragweed and Palmer amaranth are among the most difficult weeds to control in many Midwest soybean fields. These weeds have shown resistance to multiple herbicides, including glyphosate. Using multiple modes of action in a timely manner is key for effective control throughout the season.

If your customers still have time to apply a preemergence herbicide, Sonic® herbicide is a valuable tool that offers two nonglyphosate modes of action to provide long-lasting residual control. It’s proven to deliver long-lasting, broad-spectrum control to prevent weeds from invading soybean fields.

If soybeans are already emerging in your area, FirstRate® herbicide is a flexible and economical option for preemergence and postemergence control of broadleaf weeds.

If soybeans are already emerging in your area, FirstRate® herbicide is a flexible and economical option for preemergence and postemergence control of broadleaf weeds. FirstRate can be tank-mixed or applied sequentially with glyphosate to help control common ragweed, lambsquarters and marestail. DuPont EverpreX herbicide also provides a wide application window from preplant to postemergence up to 90 days before harvest. EverpreX helps soybean farmers gain residual control of many weeds and grasses resistant to ALS, PPO and glyphosate.
